TO ALL WHOM-IT MAY CONCERN;

Be it known that I, N. B. SORNBQRGER, of Northampton, in the county of Hampshire, and State of Massachusetts,have'invented a new and improved Combined Catheter and Syringe; and I do hereby declare that the following is a -full, clear, and exact description thereof, which will enable those skilled in vthe art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The combined catheter and syringe embraced in the present invention is provided with a collar on its body' or cylinder, susceptibleof adjustment at pleasure, and thus, througha stem or rod connecting it with a collar arranged to'slide upon the discharge-tube or Vpassage of thesyringeenabling such collar on the discharge-tube to be adjusted to any point, according to the distance which it is required or desired for vthe discharge-'tube to pass into the system, whereby, when used by unskillful operatives or persons, rendering it almost to cause injury to the parts of the system; and, also, the body or cylinder of the syringe is pr'ovided with loops for receiving straps, by means of which it can be fastened or strapped to the body when used as a catheter. In the accompanying plate of drawings, my improved combined catheteriand syringe is illustrated, the figure being a partial side view' and longitudinal section of the same. l p y A, in the drawings, represents the body or cylinder of the syringe, in which is arranged to move a plunger or piston, as in ordinary syringes. B, the discharge-tube to the body A,which tube is screwed into one end, C, of the same. D, a collar, arranged on outside of cylinder A, so as to be adjusted in position thereon, and being adjusted, set, or lfastened by a. set-screw, E, of the same. F, a rod 'or stem, hooked at one end in the collar D, from which, being extended along the side of the cylinder toward its end-carrying the discharge-tube, it is fixed at such end in and to a. collar or disk, G, arranged to slide on such tube. '.lhis collar or dislc G, when Y.

the' syringe is inserted in the system, acts as a stop thereto, and .if properly adjusted on th'e discharge-tube, pref i vents all possibility of injury to any part or parts of the system. H, loops secured to bodyAof syringe, upon opposite sides thereof,'to which loops or straps areto b-e attached for fastening the syringe inposition upon the person when used as a. catheter.

I claim as new, and desire to secure by Letters Patent- The slide or collar on the body lto a syringe, in combination with a collar in the discharge-tube, when the two are connected together and arranged for operation substantially as and for the purpose described.

Ialso claim the loops applied to the cylinder of a'syringe for receiving fastening-straps, substantially as described.
